The K&N Typhoon cold air intake for Honda Civic 1.8L (2012–2015) uses a mandrel-bent aluminum intake tube paired with a washable, reusable high-flow oiled cotton filter to deliver measurable increases in horsepower and torque. The oversized conical filter can allow up to 100,000 miles between services under normal highway driving; a heat shield protects intake air and most systems install in under 90 minutes.
